The Nagra HD PHONO, following the launch of the Reference turntable and Nagra MC-4 moving-coil cartridge, is a state-of-the-art phono stage. It features a two-chassis design: one housing the delicate phono stage circuitry in a CNC machined aluminum chassis, and the other containing a supercapacitor-based power supply. This advanced power supply, based on the HD PREAMP and HD DAC X, charges faster and handles higher current loads more efficiently than traditional battery-based power supplies.


The HD PHONO incorporates a damped, constrained layer platform and four isolator damped towers for superior vibration resistance. It is a dual-mono, pure Class A design with 100% tube stages, utilizing 4x EF806S and 2x E88CC tubes. It features custom-made input transformers with cryogenically treated Cobalt cores, providing 26 dB of gain and an overall adjustable gain of up to 68.5 dB.


Key features include:

  • Custom Input Transformers: 26 dB gain, cryogenically treated Cobalt cores.
  • Adjustable Gain: Up to 68.5 dB, adjustable by +/- 6dB.
  • Loading Adjustability: Remote-controlled cartridge load adjustability from 10 to 390 Ohms in 5 Ohm steps.
  • Inputs: 2x MC inputs on RCA, 1x MM input on RCA, 1x optional input for future custom transformers.
  • Equalization Curves: RIAA, TELDEC, NAB 100µS, VICTOR EUR, VICTOR USA.
  • Power Supply: Separate chassis with supercapacitor module for silent power delivery.


The HD PHONO ensures optimal cartridge matching and superior sound performance, confirmed by ear from the comfort of your listening chair.
